| W/S. C/Hn.{F. C. Honeyman - Retail orders} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} V8260 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}1/LG9.2.26. SCUTTLE VENTILATION. X.8260 With reference to C/Hn{F. C. Honeyman - Retail orders}2/MH{M. Huckerby}30.1.26. When we conducted our tests on louvred bonnets we did not obtain any information as to the effect that this fitting would have on scuttle ventilators. We should not anticipate however that the amount of hot air escaping from the XXXX louvred bonnet would have an appreciable affect upon the temperature of the air entering the scuttle ventilators.
